Metal Caps

These 18mm metal container caps are designed as a secure screw lid closure for packaging applications that use an 18-400 thread finish. Each cap is made from metal and finished in silver with a matte surface, giving compatible containers a clean and understated appearance. The screw lid includes a plastisol liner, which the supplied product information describes as helping create an airtight seal so packaged items can remain fresh and protected.

Supplied in a 250 count pack, these silver metal caps are suited to packaging teams that need a consistent quantity of matching closures for production, storage, retail preparation, or inventory replenishment. The 18mm inner diameter and 18-400 thread finish are the key sizing details to review before pairing the cap with a container. These caps are not child resistant. Buyers should therefore use them only in applications where a standard non child resistant closure is appropriate. The 250 count configuration also provides a cost effective option for businesses purchasing container caps in practical commercial quantities.

18mm Screw Lid Features and Packaging Applications

• Metal construction provides a durable closure format for routine packaging use.
• Silver color and matte surface finish offer a neat presentation for compatible containers.
• Plastisol liner supports the airtight sealing function described in the supplied product information.
• 8mm inner diameter and 18-400 thread finish provide the main compatibility references for container selection.
• Screw lid design provides a familiar closure format for packaging and storage workflows.
• Each pack contains 250 caps for commercial inventory planning and repeat packaging tasks.

For dispensaries, packaging suppliers, processors, manufacturers, retailers, and other commercial packaging operations, these metal screw lid caps can serve as a straightforward closure choice when the container specification matches the 18mm size and 18-400 thread finish. Businesses looking for wholesale metal caps or bulk container caps should still confirm container compatibility before ordering, since the supplied data does not provide an exterior diameter or overall cap height. Because the product is listed as not child resistant, it should not be selected where a child resistant closure is specifically required.

The labeling diameter refers to the usable amount of space on the top surface of a cap for a round sticker. If opening and closing instructions are included on a cap, the usable labeling diameter is reduced so the sticker does not obscure debossed or embossed text. The supplied product information does not provide a numeric labeling diameter, overall diameter, height, or circumference for this cap, so those values remain unspecified rather than estimated.
